An additional two individuals have been arrested related to a robbery at London's Heathrow Airport where 21 people were injured by what is thought to be pepper spray, according to police.
A 24-year-old man, was arrested in Lambeth on suspicion of robbery and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. They both are still being held, the force said.
The arrests come after an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the incident, a pair of female travelers had stolen from them their luggage after getting out of a parking garage elevator.
A toddler aged three was among the those hurt in the event. A total of five individuals went to hospital for medical care and have since been discharged.
Officers arrested a man in his thirties on suspicion of theft and assault near the scene. He was subsequently released under investigation as the investigation proceeds.
Authorities were called at about 08:10 GMT after reports came in regarding several people hurt by an irritating chemical believed to be an irritant spray.
The assault - an event that authorities stated was a standalone incident and not considered an act of terror - caused delays to rail services and the temporary shutdown of the main airport tunnel and the T3 parking facility for a short time.
